IPC: A61K35/22
Filed: 1997-03-21
Abstract: Implantable beads which are made of agarose and collagen, and/or coated with agarose have incorporated within samples of cells.  The cells produce diffusible biological products. The beads may be used as implants to modulate a recipient's immune response. The beads may also be used in an in vitro context to encourage specific types of cells to grow, to produce desirable products in culture, or to suppress growth of certain cells. The implants may also suppress growth of certain cells following administration to a subject.

Abstract: The purpose of the invention is to be used as a highlighting paper in the hairdressing industry. Highlighting papers are used by hairdressers for a process known as highlighting wherein strands of hair are coloured with a colour formulation and kept divided from the uncoloured hair by these highlighting papers.   The most popular material used for highlighting is aluminum foil. Aluminum foil is a great insulator of heat however the foil is very heavy and tends to drag and pull away from the hair causing demarcation lines in the hair moreover aluminum foil is not reusable so that every time a head of hair is finished being highlighted all of the dozens of papers are thrown away and over the duration of many processes this can add up to hundreds and hundreds of papers each week.   The invention will eliminate these two problems while allowing for all of the positive properties of aluminum foil.     The invention is a material comprised of a thin sheet of aluminum foil being laminated with a poly substance being either polyurethane, polyester or polypropylene. These three substances are all substantially lighter than aluminum foil since only a small amount of aluminum foil is needed to maintain the heat retaining qualities of the foil so when laminated with one of the poly substances the papers become noticeably lighter than aluminum foil thus, the invention will not weigh down on or drag down on the hair causing lines of demarcation like the foil.     The invention is reusable unlike foil because the three poly substances when laminated with aluminum foil can be rinsed and wiped clean of any colour formula and used again, this factor would eliminate an uncountable amount of waste produced by each stylist in a salon and save a lot of money for the salon and it's hairstylists.
Patent CA-2258237-A1 (CA)
Inventor: CUNNINGHAM EDMUND C
IPC: F04B47/08
Filed: 1999-01-08
Abstract: A uniquely designed hydraulic cylinder adapted to a conventional oil well, bottom hole pump. This cylinder employs separate confined hydraulic fluid supply for the gland port and the end port which allows the hydraulic plunger to actuate the BHP  plunger and traveling valve by alternately powering the port supplies until they have achieved their full travel. The automatic repetitive action of the actuator is achieved with pressure sensitive supply relays that reverse the port flow when the pump has reached its' top stroke or bottom stroke and causes the hydraulic supply to pressure up. These controls are mounted on the surface hydraulic supply.

Patent CA-2269346-A1 (CA)
Inventor: HUANG HONG
IPC: H02M7/5387
Filed: 1999-04-14
Abstract: A DC-AC inverter is defined as an electrical instrument to convert a DC  (direct current) source to an AC (alternating current) output. In such an instrument, the electric energy can flow from the DC source to the AC output, or from the AC output to the DC source. But the latter energy-flow direction is not the intentional design direction for the inverter. This phenomenon exists when the voltage level at the DC source is lower than the voltage level at the AC  output, for example, when the inverter is used in the wind energy conversion systems at low wind conditions, or when the inverter is used in the photovoltaic solar energy conversion systems at cloudy time. In such systems, the AC output is connected to the electric power lines, or the electric grid as the technical term used by electric utilities. The energy-flow from the AC to the DC can cause substantial reactive power, usually in lagging form, interference with the electric power delivery, increasing energy losses and reducing the energy conversion efficiency of the wind energy conversion systems or photovoltaic solar energy conversion systems.   In this invention, the electric energy-flow unique direction from the DC to the AC is secured by adding a reverse blocking device, for example, a diode in series connection in between the DC source and the inverter. By adding such a reverse blocking device, for example a diode, defined as the blocking diode, the electric energy-flow is confined only from the DC  source to the AC output no matter what the DC voltage level is. As a result, the reactive power output of the inverter and energy losses are reduced, and the system energy conversion efficiency is increased. A small fraction of the previous DC capacitance will be moved to the position after the reverse blocking device, or an additional capacitor will be added at the position after the reverse blocking device to smooth the inverter current commutation and reduce the voltage tension on the inverter switching devices. Other options to reduce the voltage tension may also include a parallel connected switch with the reverse blocking device and a voltage varistor.

Abstract: The sender of a message is able to specify to the recipient's messaging system or to the sender's own messaging system a reply time at which the sender wishes to be informed of whether or not the recipient has accessed the sent message. The reply time is included in the message. Upon occurrence of the response time, the recipient's messaging system checks if the recipient has accessed the message, and if not, whether the recipient's present schedule is available. It then sends a reply, with the schedule if it is available, to the sender. Upon occurrence of the response time, the sender's messaging system checks if a reply has been received from the recipient, and if so, whether it indicates that the message has been accessed and whether it contains the recipient's schedule. It then notifies the sender accordingly. The schedule preferably contains information that enables the sender to contact the recipient by other means.

Title: Ambient energy powered display
Inventor: PREAS BRYAN T
IPC: G09G3/34
Filed: 1999-09-13
Abstract: A bistable display device that is powered only by ambient energy. Ambient energy is collected by an ambient energy receiver which converts the ambient energy into an operating signal and provides the operating signal to a controller. The controller drives the display device based on the operating signal. A user can create a custom display by fixing customizable patterned electrodes to the display. A display controller uses a self-starting oscillator. The oscillator outputs a clock input signal wave to a ripple counter and a voltage signal to a voltage doubler. The voltage doubler outputs a stored charge signal to a transformer concurrently with a clock pulse that is output by the ripple counter to change a state of the voltage output from the transformer to conductive electrodes within or on the display. The voltage output from the transformer applies an electric field across the display in the portions of the display covered by the conductors to switch the image on the display. As the display is bistable, if the ambient energy receiver and controller are detached from the display or there is an insufficient amount of ambient energy, the image on the display will stop switching, but will not fade.

Abstract: An apparatus and method for enabling the routing of wide grooves and rabbets onto the sides, edges, or ends of boards, using a hand-held router. The apparatus comprises a main body platform with a pair of fence feet mounted on the underside. The fence feet act as guide fences, supporting feet, or both, to guide the router over the workpiece to obtain the desired cut. Calibration reference points on the main body platform and on the fence feet allow the fence feet to be adjusted quickly and accurately for various widths of grooves and rabbets, and for a number of different router bit sizes. The operating height of the main body platform may be adjusted by adding fence feet soles and spacers onto the bottom of the fence feet.
